Implementations

impl Type

pub fn as_result(&self) -> Option<(&Type, &Type)>

Extract Ok and Err types if this is Result<T, E>

pub fn has_lifetime(&self) -> bool

Check if type contains a lifetime anywhere in the tree

pub fn has_named_lifetime(&self, name: &str) -> bool

Check if type contains the named lifetime anywhere in the tree.

pub fn has_non_named_lifetime(&self, name: &str) -> bool

Check if type contains any named lifetime other than name.

pub fn has_elided_reference_lifetime(&self) -> bool

Check if type contains any &T reference without an explicit lifetime.

We require explicit 'roam for borrowed RPC return payloads.

pub fn contains_channel(&self) -> bool

Check if type contains Tx or Rx at any nesting level

Note: This is a heuristic based on type names. Proper validation should happen at codegen time when we can resolve types properly.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Type

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Parser for Type

fn parser(tokens: &mut TokenIter) -> Result<Self>

The actual parsing function that must be implemented. This mutates the tokens iterator directly. It should not be called from user code except for implementing parsers itself and then only when the rules below are followed.

impl ToTokens for Type

fn to_tokens(&self, tokens: &mut TokenStream)

Write &self to the given TokenStream.

fn to_token_iter(&self) -> TokenIter

Convert &self into a TokenIter object.

fn into_token_iter(self) -> TokenIter

where Self: Sized,

Convert self into a TokenIter object.

fn to_token_stream(&self) -> TokenStream

Convert &self into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self into a TokenStream object.

fn tokens_to_string(&self) -> String

Convert &self into a String object. This is mostly used in the test suite to compare the outputs. When the input is a &str then this parses it and returns a normalized String.
